Paper Abstract

Space navigation and high performance instruments of observation (having a tiny field of view) demand higher speed and accuracy in computing orbital elements for natural or artificial near-Earth objects. The most important perturbations that act on these celestial bodies are: non- centrality of the gravitational field, Sun and Moon attraction, air drag and solar radiation pressure. Taking into account these perturbations and how they affect the orbital elements, we developed software based on semi- analytical methods, used for the prediction of motion of near-Earth natural or artificial celestial bodies. In order to guide and control the observing instrument it is enough to connect it to the computer and to `translate' the orbital elements given by the software into celestial co- ordinates.
